EPM7256EQC160-12 Visão geral
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like logic blocks (called Logic Array Blocks, or LABs) on a single chip, connected through a programmable interconnect matrix. CPLDs sit between simple SPLDs (PAL/GAL) and FPGAs in the programmable logic hierarchy, offering predictable timing, low power, and fast I/O-to-I/O propagation delays. The MAX 7000 family was Altera's second-generation EEPROM-based CPLD architecture and is widely used for glue-logic, bus interfacing, address decoding, and control state-machine replacement.
Key features of the EPM7256EQC160-12 include 16 Logic Array Blocks, 256 macrocells, 132 I/O pins, in-system programmability via JTAG, and 5 V tolerant I/O with 3.3 V compatibility. The device delivers up to 90.9 MHz maximum operating frequency with a 12 ns tPD, making it well suited for legacy 5 V system designs. Its non-volatile EEPROM configuration cell means the part retains its logic implementation across power cycles without external boot memory.
The MAX 7000 architecture is based on a sum-of-products logic array with macrocell flip-flops, programmable interconnect, and per-pin output enable control. With 16 LABs of 16 macrocells each, the part provides 256 flip-flops for sequential logic. Programmable interconnect delay is fixed (unlike FPGA routing), giving deterministic, predictable timing that simplifies static timing analysis in control and interface designs.
Typical applications include 5 V system glue logic, address decoding for microprocessors and DSPs, bus interfacing (ISA, PCI, VME), state-machine replacement, industrial control boards, and telecom infrastructure requiring non-volatile fast-turn-on logic. The 132 I/O count makes it a useful integration point for peripheral bridging in legacy designs.
When designing with this part, note that it is part of the mature MAX 7000 family: most PCBs that used it can drop in faster speed grades (-7, -10) or temperature-extended variants (-15I, -20) provided the package and pinout match. Designers should consult the Quartus/MAX+PLUS II support notes for legacy software compatibility. This page combines distributor pricing, drop-in alternative cross-references, and practical design guidance not found in the original datasheet.

Aplicações típicas
EPM7256EQC160-12 é adequado para 6 aplicaçãos: 5V System Glue Logic, Microprocessor Address Decoding, Industrial Control State Machines, Telecom Backplane Bridging, Legacy PCI / ISA Bridge Logic, Test & Measurement Front-End Logic.
5V System Glue Logic
The EPM7256EQC160-12 is ideally suited for 5 V system glue-logic consolidation, replacing discrete 74LS/74HC TTL with a single programmable device. Its 12 ns tPD and 90.9 MHz fMAX comfortably handle 33-50 MHz bus cycles in legacy 5 V architectures such as VME, ISA, and PC/104, while the 132 I/O pins aggregate dozens of decode, latch, and mux functions onto one chip. The 256 macrocells accommodate complex address maps with multiple chip-select outputs and registered handshake logic, and the EEPROM non-volatile configuration eliminates external boot PROMs. Power dissipation stays in the 0.5-1.5 W typical range at 5 V, far below FPGAs of similar logic capacity.
Recomendado
Microprocessor Address Decoding
The 132-I/O EPM7256EQC160-12 consolidates full address decoding for embedded microprocessor systems, generating chip-select signals for memory and peripherals from a single device. With 16 LABs and 256 macrocells, designers can implement wide product-term decode trees for both memory and I/O maps simultaneously, plus wait-state generators and bus arbitration logic. The 12 ns propagation delay leaves comfortable margin for one-clock-state bus cycles at 33 MHz, and the JTAG in-system programmability enables last-minute board-revision fixes without swapping the part. Operating from a single 5 V rail, the part integrates cleanly with legacy 68k, x86, and PowerPC host designs.
Recomendado
Industrial Control State Machines
In industrial control PLC and motor-drive boards, the EPM7256EQC160-12 replaces banks of PAL/GAL devices with a single non-volatile state-machine engine. Its 256 macrocells implement complex multi-state sequencers for conveyor control, machine-tool interlocks, and process automation while the 132 I/O count interfaces directly to opto-isolated 24 V field I/O through 5 V level shifters. The MAX 7000 architecture's deterministic interconnect delay simplifies IEC 61131-3 timing analysis, and the commercial 0-70 °C range covers most factory-floor enclosures. JTAG re-programmability enables field firmware updates via boundary-scan without removing the part.
Recomendado
Telecom Backplane Bridging
Telecom infrastructure designs based on H.110 CT bus, MVIP, and SCSA used the EPM7256EQC160-12 to bridge time-division-multiplexed (TDM) streams between framer ICs, DSPs, and TDM switches. With 132 I/O pins and 12 ns tPD, the part handles 8 Mbps E1/T1 stream multiplexing, clock distribution, and frame-alignment logic without external glue. The 5 V supply matches legacy telecom line-card power rails, and the PQFP-160 footprint integrates into existing backplane daughter-card layouts. The non-volatile EEPROM configuration guarantees instant-on operation after power-cycle events that are routine in central-office equipment.
Recomendado
Legacy PCI / ISA Bridge Logic
The EPM7256EQC160-12 implements legacy PCI target devices, ISA bus arbiters, and PCI-to-ISA bridges in industrial single-board computers and instrumentation. With 256 macrocells, the part encodes full PCI configuration-space decoding plus ISA bus controllers and DMA handshake logic in one device. The 12 ns tPD meets PCI 33 MHz clock-to-output requirements with comfortable margin, and the 132 I/O count directly drives PCI bus signals plus peripheral chip-selects. JTAG boundary-scan compliance simplifies board-level interconnect testing per IEEE 1149.1.
Recomendado
Test & Measurement Front-End Logic
In oscilloscope, logic-analyzer, and bench-instrument front ends, the EPM7256EQC160-12 implements range-selection muxes, ADC timing generators, calibration state machines, and display-scan logic. The 132 I/O count connects directly to 8-16 channel analog muxes and LED/LCD driver arrays, while 256 macrocells encode the full measurement-cycle state machine with deterministic 12 ns step times. The EEPROM non-volatile configuration ensures instant boot into the calibration state, and the JTAG interface allows in-system firmware updates during factory calibration procedures. Single 5 V operation simplifies mixed-signal board power architecture.

Principais diferenciais

- Drop-in pin-compatible upgrade path within the same PQFP-160 footprint (vs EPM7256AQC208-7)
- Faster propagation delay available in the same footprint (vs EPM7256EQC160-15)
Notas de projeto
Estimated: At 5 V VCC, ICC quiescent is approximately 100-300 mA (depends on logic utilization and toggle rate). Bulk-decouple each VCC pin (33, 69, 97, 131) with a 0.1 µF ceramic placed within 5 mm of the pin, and add one bulk 10-47 µF tantalum or aluminum-polymer capacitor near the package. The MAX 7000 family does not require external configuration memory, but in-rush current during EEPROM programming can briefly exceed 200 mA per VCC pin - size your regulator accordingly.
The PQFP-160 package has 0.65 mm pitch gull-wing leads with a 28 × 28 mm body. Use a 4-layer PCB with one solid ground plane under the part and one 5 V power plane on an adjacent layer; route all 132 I/O signals on the outer layers with matched impedance for clock and JTAG signals. Leave at least 3 mm clearance around the package for inspection and rework. JTAG signals (TDI, TMS, TCK, TDO) must be length-matched within 25 mm to avoid boundary-scan shift-register glitches.
Do not confuse the EPM7256EQC160-12 (5 V commercial, PQFP-160) with the EPM7256AQC208-7 (also 5 V commercial but PQFP-208 with 7.5 ns tPD) - the pin counts and footprints differ. Do not assume any modern Quartus version supports MAX 7000 - use Quartus 13.0sp1 or MAX+PLUS II 10.2 as your design entry. If migrating legacy designs, verify the JTAG chain order against the BSDL file before production programming.
